2.4 crank pulley crizzap
 

so it looks like the crank pulley on a 2.4 is held on by 4 bolts and a giant center bolt. and that bolt is a bitch!

i have no air impact tools, btw.

i turned the crank until i could fit a wrench inbetween a crank counterweight and some block webbing. still couldn't apply enough torque to the bolt, because the whole block wants to roll over. i was thinking about putting it on the engine stand and trying again, but this method seems a little too ghetto even for me!

any ideas on how to get that damn crank bolt out? the other end of the crank is naked, no bolts, no flywheel. and the block has no pistons/rods in it.

You're in luck. The large bolt does not hold the crank pulley on, just the four small bolts. The large bolt holds the lower cog for the timing belt. You pretty much need a real impact gun and air if you actually need to get that bolt out for some reason.

really? thats how the dsm was. i could have sworn that large bolt was absent from the dsm. hrmmmm.

i'm going to the garage now to yank on that mofacky of a pulley.

Re: 2.4 crank pulley crizzap
 

just tried...and failed.

that pulley/damper is most definetly held on by that large bolt. it is not like a dsm. :(

Big air impact gun.

Yup, only if it was still in the car or atleast assembled.

Have you tried hitting the breaker bar with a deadblow? Do you know anyone with an electric impact? Some of those are good for 400ft lbs, it may work.

Or , put it in your truck and drive to the nearest shop and ask for a hand. Find the guy who has an IR Titanium, if that wont get it off nothing will.

Pretty 97% sure it's just the 4 borrrts Joe. That's all I did on the other 2.4's I took apart.

joe..bring it into work, and i'll get it off for ya. I got that ti titanium the above mentioned.

Only take out the four bolts Joe ;)

I had to go and buy a 600 ft/lb impact when I couldn't get a pulley off a Honda. That puppy does the trick every time. You can also crank up your compressor a bit more for special stuff like that as well. I normally have mine at 100 psi, but I crank it up to ~130 psi if I have a bolt that won't come loose otherwise.

And the 6-bolt 2.4 I have uses the DSM crank pulley, trust me, it's only the four bolts. I had the pulley and the timing belt cog all come off and bend some valves at the SO a few years ago. Now I always loctite the large bolt.

Re: 2.4 crank pulley crizzap
 

Liar. It is a tight fit, but the pulley will come off with large bolt on there. The washer on the large bolt is very close to the size of the inside of the pulley though. If there is corrosion it can take some persuasion to get it off. You might want to try an electric impact on it. I have a pretty beefy one (7 amps) that might have a chance at taking one off. Probably not though.

Damn Joe, you're an engineer, you should be able to figure something out. :p

Re: 2.4 crank pulley crizzap
 

I usually whack the pulley with a rubber mallet on each side so it rocks back and forth. It'll come off.

We know what you whack.
